The idea that fiction doesn't have as much value as non-fiction is so stupid and exhausting.

Science fiction, for example, is often invaluable for commentary on present and future issues. Climate change, politics, gender, artificial intelligence, etc. There is no limit to what science fiction can imagine, and that imagination can be used incredibly well for thought-provoking literature that helps people grow. A Clockwork Orange or a Canticle for Leibowitz are excellent examples.

Fantasy is similar in how it can use wildly imaginative situations to expand on interesting ideas. Terry Pratchett's Discworld does this CONSTANTLY. His book Small Gods is a hilarious critique/satire on religion and the various hypocrisies of religion. His work is even profound enough to be referenced as an economic theory of socioeconomic unfairness (Vimes Boot Theory).

That isn't to say that every work of fiction needs to be profound. There is value in a beautiful story. In a creative story. In a funny story. Art done well is worthwhile.
